Sleeping bag pillow structure

ABSTRACT

A sleeping bag pillow structure comprises a sleeping bag with a pillow portion wherein at one side of the pillow portion is fixed a sack-like retaining element with an opening edge through which an inflatable pillow having a deflating/inflating nozzle attached thereto can be freely accommodated into and retrieved from the sack-like retaining element so that no other pillow is separately carried for the sleeping bag, and the inflatable pillow when deflated via the deflating/inflating nozzle can be synchronically rolled up along with the sleeping bag for easy storage, facilitating more convenient application and carriage of the sleeping bag. Besides, the inflatable pillow when saturated with air is accurately limited by the sack-like retaining element and stably held in place at the pillow portion of the sleeping bag without randomly sliding around due to the change of sleeping postures so as to improve the sleeping quality of a sleeper thereby.

BACKGROUND OF THE INVENTION

The present invention is related to a sleeping bag pillow structure, comprising a sleeping bag with a pillow portion wherein at one side of the pillow portion is attached a sack-like retaining element with an opening edge, into which an inflatable pillow having a deflating/inflating nozzle attached thereto can be accommodated so that no other pillow is separately carried for the sleeping bag thereof, and the inflatable pillow can be synchronically rolled up along with the sleeping bag for easy storage, facilitating more convenient application and carriage of the sleeping bag. Besides, the inflatable pillow limited by the matched sack-like retaining element in position can be stably held in place at the pillow portion of the sleeping bag without randomly sliding around due to the change of sleeping postures so as to improve the sleeping quality of a sleeper thereby.

A conventional sleeping bag on the market features a bag-like main body with a pillow portion that forms a flat and soft surface with the bag-like main body thereof. As a result, a pillow article must be separately carried for the application of the conventional sleeping bag, which can cause inconvenience in application and carriage thereof. And in case the sleeping bag is rolled up for storage, the separate pillow article tends to increase the volume of the sleeping bag and pose a problem in the storage of the sleeping bag thereof. Thus, the pillow article must be separately kept away, which can take a lot of extra space for the storage thereof. Besides, the pillow article is simply placed onto the pillow portion of the bag-like main body without any limitation effect provided, which can make the pillow article randomly moving and sliding around due to the change of sleeping postures of a sleeper and disrupt the sleep of the sleeper wakened from time to time to relocated the displaced pillow article with a bad sleeping quality thereof.

SUMMARY OF THE PRESENT INVENTION

It is, therefore, the primary purpose of the present invention to provide a sleeping bag pillow structure, comprising a sleeping bag with a pillow portion wherein at one side of the pillow portion is fixedly attached a sack-like retaining element with an opening edge through which an inflatable pillow having a deflating/inflating nozzle attached thereto can be freely accommodated into or retrieved from the sack-like retaining element so that no other pillow is separately carried for the application of the sleeping bag thereof, and the inflatable pillow can be synchronically rolled up along with the sleeping bag for easy storage, facilitating more convenient application and carriage of the sleeping bag thereof.

It is, therefore, the second purpose of the present invention to provide a sleeping bag pillow structure wherein, depending on the sleeping habits of a sleeper, the inflatable pillow can be appropriately adjusted in the air-saturated hardness and softness so as to enhance the comfort of the sleeper and achieve more humane design thereby. Besides, via the design of the sack-like retaining element to accommodate the inflatable pillow therein, the inflatable pillow swollen with filled-in air can be precisely limited by the matched sack-like retaining element in position and stably held in place at the pillow portion of the sleeping bag without randomly moving or sliding around due to the change of sleeping postures so as to improve the sleeping quality of the sleeper thereof.

It is, therefore, the third purpose of the present invention to provide a sleeping bag pillow structure wherein when the sleeping bag is to be cleansed, due to the opening edge thereof, the inflatable pillow can be retrieved from the sack-like retaining element without been soaked in water and washed together with the sleeping bag so that the foams of detergent won't infiltrate into the inflatable pillow and cause the untidy phenomena of water stains and odor during the cleansing process of the sleeping bag for easy drying of the sleeping bag as well as the extension of the using lifetime of the inflatable pillow to achieve the best using state thereof.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to FIG. 1 showing an exploded perspective view of the present invention (accompanied by FIG. 2 showing an assembled perspective view of the present invention). The present invention is related to a sleeping bag pillow structure, including a sleeping bag 10 made up of a bag-like main body 11 and a pillow portion 12 disposed at the opening end of the bag-like main body 11 thereof wherein at one side of the pillow portion 12 (either the front side or the rear side as shown in FIG. 3) is attached a sack-like retaining element 13 with a connecting section 131 disposed thereon. The sack-like retaining element 13 can be directly sewed or fastened to the pillow portion 12 with an opening edge 132 preset at one side thereof. An inflatable pillow 14 having a deflating/inflating nozzle 141 attached thereto is provided to reciprocally match with the sack-like retaining element 13 thereby. Via the opening edge 131 thereof, the inflatable pillow 14 can be precisely accommodated into the sack-like retaining element 13 that will swell and bulge upwards along with the inflatable pillow 14 saturated with filled-in air so as to provide comfortable support and cushion for head of a sleeper. In case the sack-like retaining element 13 is fixed at the rear side of the pillow portion 12 as shown in FIG. 3, the pillow portion 13 bulged by the swollen inflatable pillow 14 will rise up in a smooth and soft surface to give comfortable support to the head thereof. And, depending on the sleeping habits of a sleeper, the inflatable pillow 14 can be appropriately adjusted in the air-saturated hardness and softness to enhance the comfort of sleep and achieve more humane design thereby. Meanwhile, via the design of the sack-like retaining element 13 to accommodate the inflatable pillow 14 therein, the inflatable pillow 14 swollen by filled-in air will precisely abut against the sack-like retaining element 13 to form a comfortably smooth and wrinkleless surface therewith. Besides, limited by the sack-like retaining element 13 in position thereof, the inflatable pillow 14 is stably held in place at the pillow portion 12 of the sleeping bag 10 without randomly moving or sliding around due to the change of sleeping postures so as to improve the sleeping quality of the sleeper thereby. Furthermore, when the sleeping bag 10 is to be rolled up for storage, the deflating/inflating nozzle 141 thereof is simply squeezed to release the air filled inside the inflatable pillow 14 as shown in FIG. 4. And when the sack-like retaining element 13 becomes flattened, the inflatable pillow 14 can be easily rolled up along with the sleeping bag 10 without another keeping place required or taking up too much space for it, facilitating a spatially economical storage and convenient carriage thereof.

Please refer to FIG. 5 showing an exploded perspective view of another embodiment of the present invention (accompanied by FIG. 6 showing an assembled perspective view of another embodiment of the present invention). The present invention can also include a sack-like retaining element 13′ that, having an opening edge 132′ disposed at one side, is formed like a bag body. A connecting section 131′ is provided extending at the corresponding side of the opening edge 132′ to be sewed or fastened to an appropriate position at the upper edge of one side of the pillow portion 12 of the sleeping bag 10 (either the front side or the rear side as shown in FIG. 7) to form an individually built-in and hanging-type design thereby. And the inflatable pillow 14 can be guided through the opening edge 132′ thereof to accommodate at the sack-like retaining element 13′ therein for limiting location thereby.
